Feature/refactor-apps-string-parsing (#1152)

* Added bacnet_str functions for parsing various numeric strings.

* Renamed BACnet string API to be clearer when no stdlib function exists.

* Fixed  incompatible types - from 'BACNET_UNSIGNED_INTEGER *' to 'unsigned long *'  warning

* Changed bacnet-str-to functions to use ERANGE for error detection.

* Refactored some apps to use common string parsing for BACnet data types.

* Refactor bacapp_parse_application_data to use bacnet_string_to_unsigned for better clarity

* Added strtol for BACnetEventType.
